Except not using hexadecylpyridinium chloride handles, operation similarly to Example 1, a part that obtains being combined in the carboxyl (carboxyl of carboxyalkyl chemical fibre cellulose fiber) on the cellulose fibre forms the bandage of zinc salt.This bandage is estimated each characteristic.The result is shown in the table 1.
Following as shown in Table 1 content.
Part anionic property functional group (carboxyl) forms quaternary ammonium salt but do not have the fiber (comparative example 1) of antibiotic property slaine and a part of anionic property functional group (carboxyl) forms antibiotic property slaine (zinc salt) but do not have the fiber (comparative example 3) of quaternary ammonium salt, and is all low for the antibiotic prompt effect of Pseudomonas aeruginosa.
In addition, only flood the fiber (comparative example 2) of quaternary ammonium salt aqueous solution in fiber, antiseptic is not joined on the fiber, and therefore, not only the antibacterial effect of promptly imitating is poor, and the antibacterial effect after the washing is also poor.
Relative therewith, part anionic property functional group (carboxyl) forms the antibiotic fiber of the present invention (embodiment 1～6) of quaternary ammonium salt and another part formation antibiotic property metal, only forming the situation of quaternary ammonium salt with anionic property functional group (carboxyl) compares with the situation that only forms the antibiotic property slaine, demonstrate high antibacterial effect synergistically, particularly antibacterial effect (60 minutes with the interior antibacterial effect) excellence of promptly imitating.
In addition, antibiotic fiber of the present invention also demonstrates good antibacterial effect after washing, and antibiotic continuation is also excellent.
In addition, the anionic property functional group of fiber is compared with the situation of having used the phenylmethane ammonium with the situation of cetyl pyridinium base combination, the disengaging rate of antiseptic significantly low (comparison of embodiment 1 and embodiment 4).Therefore think, also can expect the antibacterial action that continues even the antibiotic fiber with cetyl pyridinium base and sweat etc. contact.
In addition, antibiotic fiber goods of the present invention are handled by regeneration, can recover excellent antibiotic property (embodiment 7).
